As it matures the cap becomes nearly flat. The gills are crowded and free, not attached to the stalk. They are light pink at first and remain light pink as they mature. Eventually they turn brown with age. The stalk is white, smooth, solid or hollow, 2⅜″ to 6″ tall, and The flesh is white, turning yellow when bruised. The spore print is brown. It has a disagreeable odor that has been compared to coal tar. It is poisonous, not edible. |
